Abstract

Biodiesel merupakan suatu senyawa metil ester berantai panjang yang mengandung asam lemak yang diperoleh melalui reaksi transesterifikasi. Bahan bakar alternatif ini dapat disintesis dari minyak goreng komersial dengan bantuan katalis. Katalis basa sering digunakan dalam reaksi transesterifikasi pada sintesis biodiesel. Penggunaan katalis akan meningkatkan persentase dari produk biodiesel yang dihasilkan. Katalis berfasa solid atau padat menjadi pilihan yang tepat untuk memudahkan proses pemisahan produk akhir reaksi dengan katalis. Katalis fasa padat yang dapat digunakan adalah zeolit dan bentonit alam. Penelitian ini bertujuan untuk menentukan pengaruh kinerja katalis zeolit dan bentonit yang telah diaktivasi terhadap produksi biodiesel dengan bahan dasar minyak goreng komersial serta menentukan rendemen hasil sintesis biodiesel melalui penggunaan katalis alam. Aktivasi dengan KOH dapat meningkatkan aktivitas katalisis dengan memperbesar luas permukaan dari katalis alam (bentonit dan zeolit). Analisis FTIR dan XRD terhadap katalis alam, pemurnian, aktivasi dan recycle menunjukkan adanya perubahan struktur kristalin dari katalis yang digunakan. Rendemen hasil sintesis biodiesel melalui penggunaan katalis bentonit dan zeolit berturut-turut adalah 91,75% dan 86,05%. Berdasarkan data persen rendemen hasil sintesis biodiesel, maka penggunaan katalis bentonit lebih baik di bandingkan dengan katalis zeolit. Analisis spektrum FTIR dari sintesis biodiesel yang berasal dari minyak jelantah menunjukkan hilangnya gugus OH yang memastikan bahwa reaksi transesterifikasi terjadi. Kualitas biodiesel yang dihasilkan memenuhi persyaratan Standar Nasional Indonesia (SNI) 04-7182-2006. Massa jenis biodiesel yang diproduksi menggunakan zeolit dan bentonit sebesar 868,54 kg/m3 dan 863,50 kg/m3. Sementara itu, viskositas biodiesel yang dihasilkan menggunakan zeolit dan bentonit berturut-turut sebesar 2,92 mm2/s dan 2,58 mm2/s.Comparison of Using Natural Catalysts (Zeolite and Bentonite) in Biodiesel Synthesis from Commercial Cooking Oil. Biodiesel is a long-chain methyl ester compound that contains fatty acids obtained through a transesterification reaction. This alternative fuel can be synthesized from commercial cooking oil with the help of a catalyst. Base catalysts are often used in transesterification reactions in biodiesel synthesis. Using a catalyst will increase the percentage of the biodiesel product produced. Solid or solid-phase catalysts are the right choice to facilitate separating the final reaction product from a catalyst. Solid-phase catalysts that can be used are zeolite and natural bentonite. This study aims to determine the effect of activated zeolite and bentonite catalysts on biodiesel production using commercial cooking oil as a base material and determine biodiesel synthesis yield using natural catalysts. The catalyst activation with KOH can increase catalytic activity by increasing the surface area of natural catalysts. FTIR and XRD analysis of natural catalysts, purification, activation, and recycling showed a change in the crystalline structure of the catalyst used. The yield of biodiesel synthesis by using bentonite catalyst was 91.75%. Meanwhile, the use of zeolite catalysts produced 86.05% biodiesel. Based on the percent yield data from biodiesel synthesis, the use of bentonite catalyst is better than zeolite catalyst. FTIR spectrum analysis of biodiesel synthesis from used cooking oil showed the loss of the OH group, which confirmed that the transesterification reaction occurred. The quality of the biodiesel produced meets the requirements of the Indonesian National Standard (SNI) 04-7182-2006. The biodiesel densities produced using zeolite and bentonite are 868.54 kg/m3 and 863.50 kg/m3. Meanwhile, the biodiesel viscosities produced using zeolite and bentonite are 2.92 mm2/s and 2.58 mm2/s, respectively.

Abstract

The accumulation of plastic waste and excessive use of plastic is a common environmental issue in Indonesia. Plastics are synthetic polymers that are stable, water-resistant, light, flexible, and firm but very difficult to break down by microorganisms. Decomposition of plastic waste by burning can cause other environmental issues and, during the combustion process can produce dioxin compounds that are harmful to health. An available and affordable alternative to reduce the use of plastic is by using bioplastics. Bioplastics are plastics made from natural materials that microorganisms can break down, so they are more environmentally friendly than commercial plastics. Generally, the main ingredients for making bioplastics are starch or chitosan. The source of starch used in this project comes from cassava peel waste. In this project, researchers also utilize waste from chicken eggshells. The function of adding eggshell waste is to give biodegradable plastic complex characteristics. The ratio between cassava peel and eggshell used was 1:0, 1:1, 1:3, and 1:5. With a 1:1 ratio is the most optimal. The addition of eggshells with the correct ratio (1:1) increased the ability of biodegradation of bioplastics. The results of the Tensile Strength Test of Bioplastic Samples with a ratio of 1:0, 1:1, 1:3, and 1:5 are 9.2 x10-3kgf/cm2, 4.4 x10-3 kgf/cm2, 2 x10-3 kgf/cm2, and 2 x10-3 kgf/cm2.©2022 JNSMR UIN Walisongo.

Abstract

The regular use of waste cooking oil, which has a high level of free fatty acids and carbonyl and peroxide compounds, is the background of this study, which is harmful to one's health. Using it indefinitely will harm health, including cancer, heart disease, and possibly death. We, therefore, performed research on the purification and analysis of waste cooking oil using white rice and aking rice with the batch method to detect the free fatty acid levels before and after purification and to establish the effectiveness of white rice and aking rice. Determine the utilized cooking oil's quality following filtration using adsorbent. The findings demonstrated that white rice was more effective than aking rice at reducing fatty acid levels, as shown by the acquisition of FFA levels using white rice of 0.3141% in the merchant oil sample and 0.2410% in the home oil sample. In comparison, purification with the aking rice adsorbent is 0.3474% in the merchant oil sample and 0.1374% in the home oil sample.

Abstract

Fish bones are one of the by-products of processing fish fillets. The yield produced from the process of making fish fillets produced is only about 36% and the remaining 64% is waste that is lost in each processing process. Fish bones consist of organic compounds and inorganic compounds (minerals). The waste generated from the fish processing industry has the highest calcium content in the fish body. From the point of view of food and nutrition, fish bones are very rich in calcium that humans need, because the main elements of fish bones are calcium, phosphorus, and carbonate. Thus, fish bone waste has great potential to be used as raw material for calcium-rich fish bone meals. In this study, the utilization of mackerel bones will be studied, so it is very important to know the formula for the best concentration of mackerel bone meal, to know the potential calcium content in mackerel bones. The characterization in this project is intended to determine and determine the experimental results quantitatively. The characterizations carried out in this study were atomic absorption spectrophotometer (AAS) to determine the levels of Ca, Fe, and Zn and UV-Vis spectrophotometer to determine phosphate levels in mackerel bones. The results of the average mineral levels of Zinc, Iron, and Calcium respectively were 32.425 mg/100 gr, 4.3 mg/100 gr, and 213.825 mg/100 gr. While the value of phosphate concentration in mackerel bone meal was 2784.116 ppm. This is following the standards of BPOM.

Abstract

The large number of antiseptic products on the market provide choices for people to choose alcoholic or non-alcoholic hand sanitizers. Most commercial hand sanitizers are 70% to 90% alcohol-based. For some people, the use of alcohol-based hand sanitizers is not friendly for sensitive skin. Therefore, in this study efforts were made to minimize the use of alcohol as an antiseptic agent in hand sanitizers by using lime peel extract and betel leaf extract. Betel leaves contain chemicals that are useful as antiseptic, antibacterial, and antioxidant substances. The lime peel contains flavonoid compounds that are useful as antioxidants, antiseptics, anticancer, anti-inflammatory, and antibacterial. The results showed that the extraction of lime peel was dark brown and betel leaves were blackish brown. Lime peel extraction was carried out for 5 hours using the maceration method while lime peel extraction used the reflux method. The results of the inhibition test using the Disk Diffusion Test method showed that the growth of bacteria in the sample area grew less compared to the eco-enzyme and water. While the results of the organoleptic test showed that bio-hand sanitizer products made from the lime peel and betel leaf were quite attractive to respondents.

Abstract

Natural deep eutectic solvents (NADES) are eco-sustainable, non-toxic, non-volatile, renewable, reusable, and biodegradable, and are composed of natural compounds. NADES were developed as a new-generation solvent for extracting chitin from black soldier fly (BSF) pupae, and its effectiveness for demineralization and deproteinization was determined. Here, two promising NADES, consisting of mixtures of choline chloride-betaine-xylitol (NADES A) and choline chloride-malic acid-water (NADES B), were tested. Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), X-ray diffraction (XRD), and scanning electron microscopy (SEM) were used to investigate the changes in the chemical composition of the extracted chitin. α-chitin revealed at wavenumbers 1660-1500 cm-1, in the amide group and decomposed at 330-350°C. NADES A and NADES B have a crystalline index of 91.65% and 90.65%, respectively. The chitin-NADES A and chitin-NADES B surfaces reveal the repetition of square, pentagonal, and hexagonal units (250× magnification) and fibrils (25,000× magnification). This study provides a green approach for chitin production from BSF and reveals the potential of NADES for extracting bio-polymers from natural sources.
